Grade Q1) AT the conclusion of his competition routine, an ice-skater spins in one spot
at a rate of 4.8 rotations per second. If you assume that his moment of inertia is
0.75 kg. m>, what is his angular momentum? At the conclusion of
the spin, the skater slowly and dramatically slows to a stop over 1.5 s by
dragging the toe on one skate.
a) What was the value and sign of the angular impulse on the skater?
b) What average torque did the ice exert on the skater?

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
